$1.9\cdot10^3$

Step-by-step explanation

Calculating scientific notation for a positive integer is simple, as it always follows this notation:

$a\cdot10^b$

Step 1

To find a, take the number and move a decimal place to the right one position.

so

$1900\Rightarrow1.900\text{ }$

Step 2

Now, to find b, count how many places to the right of the decimal.

$1900\Rightarrow1.900\text{ ( 3 places)}$

Step 3

finally,

Building upon what we know above,

a= 1.9

b=3 (Since we moved the decimal to the left the exponent b is positive)

replace

$\begin{gathered} a\cdot10^b \\ a\cdot10^b=1.9\cdot10^3 \end{gathered}$

therefore, the answer i

$1.9\cdot10^3$

I hope this helps you
